Abstract: 757,885. Endless chain conveyers. BUHLER GEB. March 17, 1952, No. 6863/52. Classes 78 (1) and 78 (4). In a conveyer of the en masse type comprising a plurality of sections pivotably connected end-to-end for angular movement relative to one another in a vertical plane, the conveyer extending from a support such as a tower on which the last section is pivotally mounted, two independently operable adjusting means are provided whereby the position of the first section in said vertical plane may be adjusted by complementary operation of the two adjusting means. Fig. 1 shows a conveyer system for transferring loose material such as wheat from a ship 1 to a lighter 4, comprising conveyer sections 13, 14, 15 carried by a jib 7 pivotally mounted on an axis 9 on a frame 8 which is rotatable about a vertical axis 10 on a tower 6 mounted on a pontoon 5. The jib may be swung about its axis 9 by a cable 11 passing over a guide roller 12 to a winch (not shown) in the tower. The section 13 is built into the jib 7 whilst the sections 14, 15 are pivotally mounted on the inlet ends of the sections 13, 14 respectively, each section having its own driving motor 16, Fig. 4, connected to its chain-driving sprocket 17. The conveyer 14, 15 can be raised independently of the jib 7 by a cable 19 passing over a roller 20 to a winch (not shown) in the tower 6. By adjusting the jib and the sections 14, 15 through the cables 11, 19, the foot 21 of the section 15 may be varied relatively to the axis 10 whereby a space in the hold corresponding to the opening 22 can be reached by the foot 21. The material as it is discharged from the section 13 falls through the tower to a storage bunker 24 from which it may be discharged to the lighter 4 by a chain conveyer 25 which may be pivoted about an axis 26 by a cable 27. In Fig. 5, the conveyer comprises a section 38 pivotally mounted on a section 37 which has its discharge end pivotally mounted on a carriage 39 which is movable backwards and forwards in a horizontal direction by the cable 40<SP>1</SP> of a winch 40. The section 37 may also be moved about its pivot 39<SP>1</SP> on the carriage 39 by a cable 44, the discharge end 41 of the section 37 being connected to the discharge conduit 43 by a flexible joint 42 which permits such pivotal movement. In another arrangement, Fig. 6, comprising a section 46<SP>1</SP> pivotally mounted on a section 45<SP>1</SP>, the discharge end of the latter is pivotally mounted on an axis 52 on a structure 51 which may be moved vertically along a guide 53 by the cable 54 of a winch 56. The section 45<SP>1</SP> may be moved about the axis 52 of the cable 57 of a winch 59. Material discharged from the section 45<SP>1</SP> falls through a shoot 47<SP>1</SP> connected to a telescopic shoot 49 pivotally mounted at 50. Fig. 7 shows an arrangement in which a ship is being discharged by means of two conveyers which are mounted respectively on a wharf 61 and on a pontoon 71. The wharf conveyer comprises pivotally connected sections 65, 64 hingedly suspended from a jib 7 pivotally mounted on a tower 62 on the wharf, the section 64 discharging on to a shoot 66 formed by the inner part of the jib. The pontoon conveyer comprises sections 74, 73 suspended from a jib 71 mounted on a tower 70, the part 66<SP>1</SP> of the jib forming a shoot. Specification 537 977 is referred to.
